Abstract

The internal solitary waves propagating over the shelf slope fluctuating the acoustic energy in shallow water has been widely studied. In this paper, this process is broadened into the continental slope with different gradient at different range which is linked with the shallow water and the deep water. The temporal and spatial structures of the acoustic field with the internal solitary wave passing through continental shelf to the deep region are analyzed. The variation of signal intensity at the receiver, which is caused by the moving soliton and space dependent bathymetry, shows the coupling between low modes and high modes. The location of the internal soliton waves relative to the source and the gradient of the continental slope are considered as the dominant factors fluctuating the acoustic energy received at a range of 15km by simulating the individual and joint effect of the soliton and bathymetry on the coupling coefficients.
